Kureha Shinogi

The older brother of Shinogi, he is very narcissistic and trains to develop the perfect body. He is also a surgical genius able to do surgeries that normally take several hours in only 30 minutes, though he does not have a license. He fights Baki Hanma and is destroyed in combat by him after Baki meets the people that got screwed over by him. Ironically, he is saved by one of his victims when he needed a blood transfusion after his match with Baki. In the tournament, he fights his younger brother Shinogi and though he destroys Shinogi he decides to give up to let his younger brother continue in the tournament. During that match, despite losing his eyesight when Shiogi severed two of his cords, he surgically fixed his nerves during his fight. He serves as tournament medic as the matches go on and tried to stop Jack Hammer from using any steroids only to be beaten by him. Later, he helps Jack Hammer develop new ways of getting stronger without the use of steroids. (wikipedia)
